Find Your Perfect Diamond
Made to sit flush against the engagement ring it was designed for.
Every ring is made from start to finish in our Los Angeles atelier.
F is the last grade the certificate calls colorless, and the first one where paying for that word is defensible. The rational end of the colorless band: same white, same paper, sanest price.
An F color diamond carries a trace of body color so slight that only a trained grader, working face down against master stones, can distinguish it from E and D. Face up it is indistinguishable from either. It closes the colorless band of the scale, which means it holds the word colorless on the certificate at the lowest price the word is sold for.
F is where colorless stops being a luxury and starts being a decision. Buyers who want the certificate to say colorless, for step cuts, for platinum, for their own satisfaction, land here and keep the difference. The grades above it offer the same appearance with more expensive letters; the grade below it offers nearly the same appearance without the word.
Where F sits on the GIA color scale. The full scale, grade by grade, lives in our complete color guide.
Every color decision is really a comparison with the grades on either side. Here is that comparison, made honestly.
Step up only if a higher letter matters to you. The white will not whiten.
Choose F when you want the word colorless on the certificate at its most sensible price, particularly for step cuts and white metal settings where a colorless body is on display.
Step down when the word matters less than the wallet. G reads white face up in nearly every setting, and the saving is the largest single step on the white end of the scale.
Every stone we recommend is scored by ROSI™, our gemological intelligence, built by our gemologists, with color verified by a human eye against the actual stone. Request a ROSI™ Score Report on any diamond, ours or anyone else’s.
F suits platinum and white gold, where the colorless band belongs, and it holds its own in the open facets of emerald and asscher cuts that show body color honestly. It is the colorless grade we recommend most, because it delivers everything the band promises with the least ceremony.
The setting decides how a color grade is seen. Explore our engagement ring settings, or read the shape guides in our education library for what each cut does with body color.
F is the last time the certificate says colorless, and the first time paying for it is entirely defensible.
Above F, money buys letters. Below F, it buys back real budget at a small and manageable cost in warmth. Standing exactly on the boundary, F is the honest colorless: nothing performative about it, nothing wasted. When a client tells us colorless matters to them, this is the grade we reach for first, and when it does not, we will happily show them what a G does with the difference.
